Hi All,
I would like to run a Periodic AC analysis (PAC) at frequencies around a carrier not known a priori.
That is, I have an oscillator whose frequency - of course - is to be determined by simulation. The natural way of simulating an autonomous system and get this information is with the Periodic Steady State (PSS) engine. Around the frequency point found by PSS, I would then like to run a periodic small signal analysis.
Is there a way to specify that from ADE L? I mean some 'special syntax' to use in the PAC in order to signal the simulator that he should use the outcome of the PSS, which in turn is dealing with an autonomous system (i.e. oscillator)?
I couldn't find it rapidly, but maybe somebody can give me a hint?
As a plan B, I was thinking in the direction of ADE XL, where you have a device called "pre-simulation script" which maybe could be used to first assess the oscillation frequency and then pass this info to the next, PAC, simulation as a parameter.
I have never even read about this topic so it would be helpful if anybody knowledgeable would direct me :)
Thanks!
Michele
